WebThis is called piloerection, and most mammals can do it (even you). Piloerection can be used to make an animal look bigger (think of a cat with its hair all up), but it has a temperature regulation function too. Fluffing up your fur or your feathers allows warm air to become trapped close to the skin. Shivering is another way we can produce ... WebInsulation. Another way to minimize heat loss to the environment is through insulation. Birds use feathers, and most mammals use hair or fur, to trap a layer of air next to the skin and reduce heat transfer to the environment. Marine mammals like whales use blubber, a thick …

WebBiologically speaking, piloerection is an involuntary reaction called the pilomotor reflex. It involves the contraction of tiny muscles at the base of each hair follicle called arrector pili (a name that’s based on the same roots as piloerection). This contraction results in the hairs standing up. How does vasoconstriction keep you warm? WebOne way to produce metabolic heat is through muscle contraction—for example, if you shiver uncontrollably when you're very cold.

Shivering is muscle activity that generates heat and warms the body. Similarly, some insects vibrate their wings for a while before flight, heating the muscles to the temperature at which they work best. When an animal shivers in the cold, a large amount of heat is generated in the muscles. iris arsenic rfb
